Finally, someone with realistic mileage figures. I just filled my tank up for the first time and low and behold I actually got 41.8 mpg driving with the ECON botton on without any jack rabbit starts. Basically drove it like a Granny.
I will up the tire preasure to 40psi from 34psi and see if that will make a difference in gas mileage. Overall, I am getting the mileage that was advertised on the sticker so I am happy or at least content driving this rather bland car.
